"I used this flask on a hike this summer, carrying some amaretto for a campsite treat. I tied it to a tree and dropped it in the lake to keep it cool, and when I fished it out, it had sealed perfectly. It's heavy, but I have zero concerns about leaks. A great piece of gear for trips."

"I received this today and was initially skeptical about its leak-proof claim, as it has a snap-on top instead of a screw-on one. I was ready to downgrade my rating due to leaking but upon securing the cap by twisting, I discovered it provides a leak-proof seal! Just ensure the rubber seal is seated properly and don't overfill to avoid leaks. After taking it to a concert, I’m happy to say it didn't leak so I'm giving it 5 stars now!"

I highly recommend it for anyone looking for a gift!"

They didn’t leak and came with extra sleeves for reuse. I found them to be a great price and easy to fill with the provided funnel.”

“I used these to sneak alcohol into a concert, and they were easily hidden in my purse. I was a bit worried about their size compared to real tampons, but I mixed them with actual tampons, and they worked flawlessly. They held a shot's worth of liquid without any spills. Good value, though I wish they hadn’t warped in hot water when I washed them.”

“For sneaking drinks into a nightclub in New York City, this flask was undetectable! The staff treated it like regular tampons. While the length was a bit long, it didn’t matter.

Four drinks for a low price—this is a must-have for anyone looking to save on expensive drinks while partying.”

“I have water with me during short hikes and walks with my dog. This flask fits perfectly in my jean pocket, and if needed, I can carry two! I wish I was brave enough to use it publicly for water when taking medicine.”

“The flask is a good size for slipping into my pocket and works well as a prop. It’s a bit of a novelty, but it does the job.”
